Hi. I'm trying to run simpleFoam using the low-Re turbulence models. I've run a preliminary calculation using the standard k-e model, then switched models. Each time on startup I get the following output;

followed by a stack trace. What am I doing wrong? I've tried this with both the LaunderSharmaKE and the LienLeschzinerLowRe models with the same result. From an initial inspection of the code I can't see that G is being read in (in fact I think its calculated) and its not complaining about that.

Thanks for fast reply. I will try to go on as you suggested, I know how to calculate the values.
I'm calculating my eps and k profile from measurement data, only I have no points near the wall, I was using wall functions hence, I just wanted to see the difference in the results if I change and I read in the forums to use small figures but not zero. I will read more about it.
